This is an old lesson from my old channel, but the lick is kinda cool. The thing about the Japanese scale is that it only consists of five notes, and just like in the Pentatonic scale, it pretty much trims all the fat and this way makes sure that each individual note sounds awesome in conjunction with the chord. Regarding the lick that I still call an Arpeggio even though it makes use of all five notes of the scale, but its played using Sweep picking and you still get the Arpeggio type sound so I feel that its ok to call it an Arpeggio. You can easily use it over any type of minor chord as long as it does not pertain a natural sixth or a flattened ninth. Shred on !
